Buyer Beware | Part 3: Technology and Architecture Assessment

*This is Part 3 of the [Buyer Beware M&A Series](/2023/Buyer-Beware-M&A-Series-Index/).* ## Technology and Architecture Assessment Framework While operations and people assessment focus on current capabilities and cultural fit, technology and architecture evaluation determines the long-term viability and scalability of your acquisition. This assessment goes beyond "does the code work?" to answer critical questions about maintainability, scalability, and integration complexity. A brilliant team with solid operations can still be anchored by architectural choices that limit growth or create expensive technical debt. Conversely, strong architectural foundations can accelerate post-acquisition development and enable rapid scaling. ## Code Quality and Technical Debt ### Codebase Health Assessment **Quality Indicators:** - Code organization and modular design - Consistency of coding standards and conventions - Documentation quality and coverage - Test coverage and quality - Dependency management and versioning **Red Flags:** - Inconsistent or missing coding standards - Large, monolithic functions or modules - Extensive commented-out code - Missing or outdated documentation - Low or inconsistent test coverage **Assessment Questions:** - What's the automated test coverage percentage? - How consistent are coding standards across the team? - What's the process for code reviews and quality gates? - How is technical documentation maintained? ### Technical Debt Evaluation **Debt Categories:** - **Design Debt**: Architectural shortcuts and quick fixes - **Code Debt**: Poor code quality, duplication, and complexity - **Test Debt**: Missing or inadequate test coverage - **Documentation Debt**: Outdated or missing documentation - **Infrastructure Debt**: Outdated dependencies and environments **Debt Assessment Framework:** 1. **Scope**: How widespread is the technical debt? 2. **Impact**: How does it affect development velocity and reliability? 3. **Risk**: What's the likelihood of debt causing production issues? 4. **Cost**: What would it take to address the debt systematically? ### Code Review and Quality Processes **Process Maturity Indicators:** - Consistent code review practices - Automated quality gates and static analysis - Refactoring practices and debt management - Knowledge sharing and mentoring through code reviews ## Architecture Scalability and Design ### Current Architecture Analysis **Architectural Patterns:** -
